DNA Methylation Changes in Embryo and Endosperm Derived from Interploidy Hybridizations and Effects on Transcript Levels.

(A) Genes (top panels) and TEs (lower panels) were aligned at the 5′ and 3′ ends (dashed lines), and average methylation levels in CG (left panels), CHG (middle panels), and CHH context (right panels) for each 100-bp interval were plotted.

(B) Box plots of expression changes in triploid seeds. The orange box shows expression changes of all genes with increased expression in triploid seeds, while the yellow box shows expression changes of those genes that have increased expression in triploid seeds but lose CHH methylation.
